BLANK FOB TUIBFrCLOSING CLIPS.

Application filed May 16, 1923. Serial No. 639,258.

To all whom it may concern: I

Be it known that I, ALFRED W. KATE, a citizen of the United States, andresiding at Detroit,.in the county of Wayne and State of Michigan,haveinvented a new and improved Blank for Tube-Closing Clips, of whichthe following is a specification.

This invention relates to the V-shaped clips or clamps employed to closethe filling ends of flexible tubular containers employed for vendingtooth and shaving pastes, artists oil colors, and other viscous andpasty materials, and its object is to provide a strip or ribbon fromwhich blanks for such clips may be sheared ready to be attached to thetubes.

This invention consists of a ribbon of flexible sheet metal having itsedges indented at regular intervals directly opposite each other andalso having one of'its surfaces embossed at the same regular intervals.

This invention further consists in the details of constructionillustrated in the accompanying drawing and particularly pointed out inthe claims.

In the drawing, Fig. 1 is an elevation of a paste tube showing themanner a clip is applied to the filling end. Fig. 2 is a perspective ofthe clip on a larger scale. Fig. 3 is a plan of a section of metalribbon from which such clips may be sheared.

Tubes 1' for soft plastic, viscous and semifluid materials such asshaving, tooth and other pastes, o il colors, glues-and creams areusually of tin, aluminum or other pliable metals, and are provided withscrew caps 2 at their discharge ends. The filling ends are flattened andthen folded one or more times upon themselves and the-clips 3 arepinched 0 down upon these folded ends.

The present invention consists of a thin ribbon or strip 4 of steel,brass or other comparatively non-resilient metal or alloy formed withnotches 5 alon its two edges which notches are so shape that whentheribbon is cut across between the. bottoms of these notches,.the smallblanks thus formed have rounded corners. These blanks are then folded toproduce the clips necessary to seal the tubes, one of them being shownin Figs 2, the rounded corners 6 being clearly shown, When this shearingand bending is performed by automatic machinery, the notches 5 are ofadvantage in insuring accurate feeding, shearing and bending.

In order to secure reliable bonding between the clips and the tubes, Iprefer to emboss the ribbon in the manner indicated in Figs. 2 and 3, sothat the raised devices 6 and 7 may be pressed into the softer metal ofthe tube. I further prefer these raised devices in pairs and so formthem that they will co-operate in bending the softer metal. The devices6 are shown of such size that they, together with the metal coveringthem,

will ent r the space enclosed by the raised devices Any other desiredsystem of embossing and any other formof notches in the edges of thestrip maybe employed. The width of-the sheet and the distance betweenadjacent notches will depend upon the size.

ends of container tubes having its edges notched at regular intervals,the notches of the two edges being directly opposite each other, theribbon being embossed so as to f produce raised devices on one of itssides.
